Quarkonium production at ATLAS

The production of quarkonium is an important testing ground for QCD calculations. The J/\psi\ and \Upsilon\ production cross-sections are measured in proton-proton collisions at a centre-of-mass energy of 7~TeV with the ATLAS detector at the LHC. Differential cross-sections are presented as a function of transverse momentum and rapidity. The fraction of J/\psi\ produced in B-hadron decays is also measured and the differential cross-sections of prompt and non-prompt J/\psi\ production determined separately. Measurements of the fiducial production cross-section of the \Upsilon(1S) and observation of the \chi_{c,bJ} states are also discussed.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011), Paris, France, November 14-18 2011, 3 pages, 8 figure

W/Z properties and V+jets at the Tevatron

We present a summary of recent measurements of $W$ and $Z$ properties and $W/Z$ production in association with jets in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV with the CDF and D\O\ detectors. Latest measurements of $Z/\gamma^*$ transverse momentum and are presented along with new measurements of the angular distributions of final state electrons from Drell Yan events as a way to probe $Z$ boson production mechanisms. The mass dependence of the forward-backward asymmetry in $p\bar{p} \rightarrow Z/\gamma^{*} \rightarrow e^+e^-$ interactions is measured, the effective weak mixing angle extracted, and the most precise direct measurement of the vector and axial-vector couplings of $u$ and $d$ quarks to the $Z$ boson presented. New measurements of jets produced in association with $Z$ and $W$ bosons for inclusive, beauty and charm jets are also discussed.Comment: Presented at the 2011 Hadron Collider Physics symposium (HCP-2011), Paris, France, November 14-18 2011, 4 pages, 13 figure

Production of charm and charmonium with the ATLAS detector at 7 TeV

We report on the observation of the charm mesons D^\ast \pm, D^\pm and D_s ^\pm with 1.4 nb^-1 of data, and of the J/psi-->mu+mu- resonance with 78 nb-1 of data from the ATLAS detector in 7 TeV proton-proton collisions at the LHC. The resultant signals support the high performance of the ATLAS detector as predicted from simulation and prospects for future measurements in the charm and charmonium sector.Comment: 4 pages, 11 figure

Lean healthcare assets challenge FM performance measurement conventions

Purpose; To show how Lean Asset thinking can be applied to health care facilities using different measures to compare the estates contribution to the business of health care providers. The challenge to conventional wisdom matches that posed by Lean Production to Mass Manufacturing. Methodology; Data Envelope Analysis examines the income generated and patient occupied area as outputs from the Gross Area of a Trust’s estate. Findings; The approach yield strategic comparisons that conventional FM measures of cost per m2 hide. The annual cost of an excess estate is conservatively estimated at £600,000,000(in England alone) Research limitations/implications; Further research to understand the causes of the excess is needed and is in hand. Meanwhile the research illustrates the power of an alternative way of assessing facilities performance. Practical implications Have already been demonstrated in two trusts who have used such an analysis to define strategic estates targets, Originality. The author’s are not aware of the Lean Asset perspective previously being applied to healthcare facilities. The research shows the underlying fallacy of relying on cost per m2 as the primary measure of asset performance.</p

A revised approach to performance measurement for health-care estates

The purpose of the research was to show how lean asset thinking can be applied to UK health-care facilities using different measures to compare the estates contribution to the business of health-care providers. The challenge to conventional wisdom matches that posed by ‘Lean Production’ to ‘Mass Manufacturing’. Data envelope analysis examined the income generated and patient-occupied area as outputs from the gross area of a NHS Trust’s estate. The approach yielded strategic comparisons that conventional facilities management measures of cost per square metre hide. The annual cost of an excess estate is conservatively estimated at £600,000,000 (in England alone). Further research to understand the causes of the excess is needed. Meanwhile the research illustrates the power of an alternative way of assessing facilities performance. The authors are not aware of the lean asset perspective previously being applied to health-care facilities. The research shows the underlying fallacy of relying on cost per square metre as the primary measure of asset performance. The results and discussion will be particularly useful to senior estates and facilities managers wishing to use new measures to define strategic estates targets

Complementary approaches to the ab initio calculation of melting properties

Several research groups have recently reported {\em ab initio} calculations of the melting properties of metals based on density functional theory, but there have been unexpectedly large disagreements between results obtained by different approaches. We analyze the relations between the two main approaches, based on calculation of the free energies of solid and liquid and on direct simulation of the two coexisting phases. Although both approaches rely on the use of classical reference systems consisting of parameterized empirical interaction models, we point out that in the free energy approach the final results are independent of the reference system, whereas in the current form of the coexistence approach they depend on it. We present a scheme for correcting the predictions of the coexistence approach for differences between the reference and {\em ab initio} systems. To illustrate the practical operation of the scheme, we present calculations of the high-pressure melting properties of iron using the corrected coexistence approach, which agree closely with earlier results from the free energy approach. A quantitative assessment is also given of finite-size errors, which we show can be reduced to a negligible size.Comment: 14 pages, two figure
